Rugged Liner FR6U93 Under-Rail Bedliner
The Rugged Liner FR6U93 under-rail bedliner is engineered specifically for 1993-2011 Ford Ranger short bed models, delivering drop-in protection without drilling or permanent modification. Our FR6U93 features a rugged polyethylene construction that resists impacts, UV exposure, and chemical damage while maintaining flexibility in extreme temperatures.
This under-rail design installs beneath the bed rail caps, preserving your Ranger’s factory appearance while safeguarding the bed floor and walls from cargo wear. The textured non-skid surface keeps loads secure, and integrated drainage channels prevent water pooling that can lead to rust. We back every FR6U93 with our limited lifetime warranty, ensuring years of reliable bed protection.
FR6U93 specifications & fit details
Polyethylene Construction & Drop-In Design
We manufacture the Rugged Liner FR6U93 under-rail bedliner from high-density polyethylene, a material chosen for its exceptional impact resistance and dimensional stability across temperature extremes. This thermoplastic polymer absorbs impacts that would dent metal beds, distributing force across the liner’s surface rather than concentrating stress at a single point.
The under-rail design differentiates the FR6U93 from over-rail alternatives by installing beneath your Ranger’s bed rail caps, sitting flush with the bed floor. This configuration maintains your truck’s sleek profile while providing comprehensive coverage across the bed floor, sidewalls, and wheel wells. The polyethylene formulation includes UV stabilizers that prevent degradation from sunlight exposure, ensuring the liner maintains its structural integrity and appearance through years of outdoor use.
Ford Ranger Compatibility & Installation
Verified Fitment Specifications
The FR6U93 is precision-molded for 1993-2011 Ford Ranger models equipped with the 6-foot short bed configuration. This fitment covers both the regular cab and SuperCab body styles that share the identical bed dimensions during this production run. The liner contours precisely to the Ranger’s bed profile, including the factory wheel well housings and stamped reinforcement ribs.
Installation requires no drilling, cutting, or permanent modification to your truck bed. Simply remove the existing bed rail caps, position the FR6U93 liner into the bed cavity, and replace the rail caps to secure the liner in position. The under-rail lip creates compression between the liner and bed rails, holding the FR6U93 firmly without adhesives or fasteners. Most owners complete installation in under an hour using basic hand tools.
Care & Maintenance Requirements
Maintaining your Rugged Liner FR6U93 under-rail bedliner requires minimal effort thanks to the polyethylene’s non-porous surface. For routine cleaning, spray the liner with a garden hose to remove loose dirt and debris, then scrub with a mild automotive soap and soft-bristle brush. The textured surface traps some fine particles within its pattern, which pressure washing can dislodge more effectively than hand scrubbing alone.
Avoid petroleum-based solvents and harsh degreasers, which can soften the polyethylene surface over time. For oil or grease stains, use a citrus-based degreaser diluted according to manufacturer instructions, allowing 5-10 minutes of contact time before rinsing thoroughly. The UV-stabilized formulation resists fading, but parking in covered areas when possible extends the liner’s cosmetic lifespan.

Common Questions About the FR6U93 Bedliner
Yes, the FR6U93 fits both regular cab and SuperCab (extended cab) Ford Ranger models produced from 1993-2011, as long as your truck has the 6-foot short bed configuration. These body styles share identical bed dimensions during this production run.
The liner will not fit long bed (7-foot) Ranger models, which require the FR8U93 instead. You can verify your bed length by measuring from the inside of the closed tailgate to the front bed wall—short beds measure approximately 72 inches.
No, the FR6U93 under-rail bedliner installs without any drilling, cutting, or permanent modification to your Ford Ranger. The liner sits beneath your existing bed rail caps, which compress the liner’s edge to hold it securely in position.
Installation involves removing your factory bed rail caps, positioning the FR6U93 into the bed cavity, and replacing the rail caps using the original mounting hardware. This no-drill approach allows you to remove the liner in the future without leaving holes or fastener marks in your bed.
Yes, the FR6U93’s under-rail design maintains full compatibility with most tonneau covers, bed caps, and other accessories designed to mount to factory bed rails. Since the liner installs beneath the rail caps rather than replacing them, your mounting surfaces remain in their original positions.
Both soft roll-up and hard folding tonneau covers typically work without modification. If you have a specific tonneau cover model, we recommend verifying compatibility with that manufacturer, but the FR6U93’s low-profile design rarely creates interference issues.
Routine maintenance involves hosing out loose debris and scrubbing with mild automotive soap and a soft-bristle brush. The polyethylene surface is non-porous and resists staining from most cargo materials.
For stubborn stains or oil spills, use a citrus-based degreaser diluted according to product instructions. Pressure washing effectively cleans the textured surface pattern. Avoid petroleum-based solvents and harsh chemicals, which can soften the polyethylene over time. Check the drainage channels seasonally to ensure water flow paths remain clear of debris.
Under-rail liners like the FR6U93 install beneath your bed rail caps, creating a low-profile appearance that maintains your truck’s factory lines and preserves accessory compatibility. Over-rail liners extend above the bed rails with integrated rail caps, providing slightly easier installation but creating a more pronounced visual profile.
The under-rail approach reduces usable bed height by approximately 1.5 inches, while over-rail designs typically reduce it by 3-4 inches. Under-rail liners maintain compatibility with tonneau covers and other rail-mounted accessories, whereas over-rail liners often interfere with standard accessories.
Yes, every Rugged Liner FR6U93 includes our limited lifetime warranty that covers defects in materials and workmanship for as long as you own your Ford Ranger. This warranty protects against manufacturing defects, cracking, and structural failure under normal use conditions.
The warranty does not cover damage from accidents, improper installation, or misuse. Complete terms and conditions are included with your liner shipment. If you experience any warranty-eligible issues, contact our customer service team with your purchase information and photos of the concern.
The FR6U93 significantly reduces rust risk by protecting your bed floor and sidewalls from scratches, impacts, and moisture exposure that initiate corrosion. The integrated drainage channels prevent water pooling that accelerates rust formation on underlying metal.
However, if your bed already has rust damage or paint chips before installation, the liner will cover but not repair existing corrosion. For maximum rust prevention, inspect your bed and address any existing damage with touch-up paint before installing the FR6U93. The liner’s UV-stabilized polyethylene won’t degrade or crack, maintaining continuous protection for years.
